High-purity alpha-alumina powder offers optimized thermal stability, superior mechanical reinforcement, and enhanced chemical resistance. Designed for ceramics, coatings, and high-performance composites, it ensures precise structural integrity, extended durability, and excellent adaptability.
Product Overview
High-purity alpha-alumina powder is an extremely pure and stable nanomaterial, primarily available as a white, fluffy powder. It exhibits outstanding properties in terms of heat resistance, hardness, dimensional stability, and mechanical performance. This material is widely used in plastic, rubber, and ceramic industries as a reinforcing and toughening agent. Alpha-alumina is especially suitable for enhancing the density, gloss, fracture toughness, creep resistance, and wear resistance of ceramics and polymers. Moreover, due to its excellent far-infrared emission characteristics, it is also widely used in products like synthetic fibers and high-pressure sodium lamps. Its high resistivity and good insulation properties make it suitable for applications in laser crystals and integrated circuit substrates.
